I have the vehicle listed move with a 4.3 vortex 4x4. It stalled while driving and will not start back. It gets good fuel pressure at cylinders, replaced crank position sensor, ignition module. No codes thrown, no fuses blown. It gets spark and fuel at cylinders. Please help. Thanks

We are missing something because all you need to start the engine is fuel, spark, and air all timed correctly.

So unless your timing chain broke we either have a fuel or spark issue.

If you are getting spark then I suspect we have low pressure. When you say it is good pressure, did you actually check the PSI? If so, what was it?

Also, I would suggest checking the compression to prove out it not only has compression but that the valves are opening allowing in air to be compressed. If not, then the compression will be low which means we need to look into a timing issue.

Let me know about this info and we can go from there. Thanks
